Hi Bob,
There's a good chance that the low coolant level is caused by air bubbles working their way out of the system. I've had a few new vehicles have coolant levels that dip below the minimum mark after a few thousand miles. Come to think of it, both my Escape and my '15 Transit-350 are both below the cold fill line after sitting overnight.
I'd just keep any eye on it, and if you have to keep adding coolant get it checked out.
